LOOM.

SPECIFICATION forming part of Letters Patent No. 640,706, dated anuary2, 1900. Application filed February 2'7, 1899. Serial No. 706,956. N mol-l To all whom, it may concern:

Be it known that we, GUSTAV SOHAEFER and FRIEDRICH HINKEL, of Clinton,county of Worcester, State of Massachusetts, have invented anImprovement in Looms, of which the following description, in connectionwith the accompanying drawings,is a specification, like letters andfigures on the drawings representing like parts.

In looms as now commonly constructed it is customary to stop the loomautomatically whenever the shuttle is not present, as it should be, inthe shuttle-box.

Herein we have provided a loom with means whereby whenever the shuttleis absent from the box in which it should be at either end of the laythe loom will be stopped, and so, also, should two boxes occupying aposition at the level of the race of the opposite ends of the lay eachhave a shuttle then the loom will be automatically stopped.

In accordance with our invention we combine with the lay havingshuttle-boxes at its opposite ends and carrying a hunter having twoacting portions two binder-shafts, each having at one end abinder-finger to act on a binder of a shuttle-box and at its other end aprojection, the projection of one shaft entering a hole at one end ofthe bunter-rest, while the projection of the other binder-shaft enters aslot in the said hunter-rest, the hunterrest being shown as convexed atits top. With the use of these devices the loom may be stopped whenevera shuttle is absent from the box in which it should lie at either end ofthe lay, and so, also, should two boxes occupying a position at thelevel of the race of the lay at opposite ends thereof have a shuttle.

Figure l, in partial section, shows a sufficient part of a loom with ourimprovements added to enable our invention to be understood. Fig. 2shows the dagger-rest detached.

Fig. 2 shows the double-acting bunter detached and enlarged. Fig. 3 is apartial front elevation of a loom with our improvements added, thedrawing showing chiefly parts of the lay, usual shuttle-boxes, and partscarried by the lay, together with one corner of the loom-frame and partof the breast-beam, the breast-beam and lay being broken out to savespace on the drawings; and Fig. et'is a top or plan view of the partsshown in Fig. 3, it representing, however, more of the breastbeam.

The loom-frame A, its breast-beam A, the shipper-holding plate Aextended from the loom side and having a slot'a provided with a sidenotch in which may be held the shipper-handle B,'the knock-off lever B,pivoted at B at the under side of the breast-beam, the cam --shaft Bhaving an attached toothed gear B, which meshes with a smaller gear Bfast on the crank orlay shaft 13 united with l the lay O byconnecting-rods O, the lay-shaft C the shifting shuttle-boxes C at oneside of the loom, each shuttle-box having a suitable binder a, actedupon by a spring a to normally press the binder toward the shuttle in acell of the shuttle-box, and the binder b at the opposite end of thelay, pivoted at b, the guide-plate 11*, forming part of the shuttlebox,at the right-hand end of the lay, and the shuttle b are and may be allas common in usual looms.

We have provided the lay at its under side with suitable ears or boxes 23 4 5. boxes 2 3 contain a binder-shaft 61, having at one end abinder-finger d,whichis normally kept pressed against the free end ofthe binder b by a suitable spring 01 surrounding said shaft andconnected at one end to a collar thereon, the opposite end of the springcontacting with the ear 2 or other part of the lay.

to a collar 6 fast on said shaft, while the other end contacts with somefixed part of the lay. These two shafts are connected by a daggerrest f,the shape of which is best shown in Fig. 2. This link is pivotallymounted at one end upon the projection 6 while at its other end it has aslot 8, which is entered by the projection (i a suitable cotter-pinbeing passed The through a hole in said projection to retain the linkupon said projection.

The lay has attached to it a casting or block g, having a pivot or studg, upon which is mounted a double-acting hunter composed of an arm 9having projecting, as herein shown, from its under side a hook 9 saidarm and hook being best shown in Fig. 2. The bunter is acted upon nearits pivot by a spring g which normally serves to depress the actingfront end of the hunter.

To the under side of the breast-beam We have attached astand h, having adepending apron 7t, slotted at 71 said slot receiving in it anadjustable stud h upon which is mounted a lever h having adjustablyconnected at its ing, stud 72 lower end and extended therefrom a stud hThe upper end of this lever hstands normally close to and bears againstthe end 10 of the knock-01f lever b, and the head 10 of the saidknock-01f lever is notched, as best shown in Fig 1, where the same isshown by looking at the loom from the left of the dotted line :c, Figs.2 and 3. Viewing Fig. 1,'it will be seen that there is a space betweenthe grooved edge of the knock-off lever and the project- When theshuttle is in its proper position I in one of the shuttle-boxes oppositethe level of the race of the lay, whichever box the shuttle is in willcause the binder of the box having the shuttle to turn the rock-shaft dor e and depress the projection d or c such depression of either one ofsaid projections singly lowering the dagger-rest f, so that thedouble-acting binder moves backward and forward in the space between theend 10 of the knock-0E lever and the projection if, and consequently theknock-elf lever is not moved. Should, however, the shuttle be absentfrom either box, then the spring (2 or e acting upon the shafts d or 6,will turn the binderiinger d or e inwardly, moving the binder b or ainto the shuttle-box, such movement causing whichever projection d or eis moved to lift the dagger-rest f, so that it, acting by its projectionf against the under side of the hunter, will lift the same, so that incase a shuttle be absent from both boxes the end 12 of the upper part ofthe hunter will meet the end 10 of the knock-oh? lever and turn it torelease the shipper-handle from its usual notch in the holding-plate aShould the shuttle-boxes opposite the level of the race of the lay ateach end of the reed have a shuttle in them, then in suchcase there is afault and the binders of both of said boxes, held out by the shuttles inthem, will act to turn the binder-fingers outwardly, lowering both theprojections d and c which move downwardly the rest f, permitting thespring 9 acting with the gravity of the hunter, to lower the hunter sothat its hooked part 9! in the back stroke of the lay will catch theprojection k turn the lever h in the direction of the arrow just belowit, Fig. l, causing the upper end of said lever to meet the end 10 ofthe knock-off lever, and release the shipper-handle from the loom. Inthis way it will be understood that the lay will be stoppedautomatically whenever a shuttle is absent from the box in which itshould appear, and also whenever two shuttles are presented in oppositeboxes where under ordinary circu instances there should be but oneshuttle, and it is especially this last action of stopping the loom whenthere is a shuttle in opposite boxes at the end of the lay that webelieve our invention to be essentially new and novel and, never beforeknown.

Having described our invention, what we claim as new, and desire tosecure by Letters Patent, is-

1. A lay having shuttle-boxes at opposite ends thereof and provided witha bu nter, two binder-shafts carried by the lay, each having at itsouter end a binder-finger to act on a binder of a shuttle-box, and atits inner end a projection, and a hunter-rest having one end pivoted toone of said projections and the other end joined to the other projectionby a pin-and-slot connection, combined with a shipper-handle and meansadapted to be acted upon by said bunter in either of its extremepositions to dislodge the shipper-handle and stop the loom whenever ashuttle is absent from either box in which it should be present, andwhenever two boxes at the level of the race each have a shuttle, saidbunter occupying a third position intermediate its extreme positionswhenever the shuttles are in their correct boxes.

2. A lay having a shuttle-box at opposite ends thereof and provided witha hunter having two acting positions; two binder-shafts carried by thelay, each having at its outer end a binder-finger. to act on a binder ofa shuttle-box, and at its inner end a projection, and a hunter-resthaving at one end a hole and at its opposite end a slot, and providedcentrally with a rest on which the hunter is supported, one of saidprojections entering the hole and the other the slot in the ends of thehunter-rest; combined with a shipper-handle and means adapted to beacted upon by said hunter in either of its extreme positions to dislodgethe shipper-handle and stop the loom whenever a shuttle is absent fromboth boxes at opposite sides of the lay, and whenever both boxes atopposite sides of the lay on a level with the race each contain ashuttle, said hunter occupyinga third position intermediate its extremepositions whenevera shut tle is in one of the boxes at the level of therace, substantially as described.

In testimony whereof we have signed our names to this specification inthe presence of two subscribing witnesses. 1
